Improvement in kaleidoscopes



dlnted gutter anni @Mitre MATTHIAS KELLER, OF BOSTO, MASSACHUSETTS, ASSIGN TO H IESE L F, STOUGHTON 15. HOLDEN, AND LUTHER. L. IIOLDEX2 Letters Patent No. 105,218, dated July 12, 1870.

IMPROVEMENT IN KALEIDOSCOPES.

The Schedule referred to in these Letters Patent and making pari of the same.

To all whom it may concern:

Be it known that I, MATTHIAS KELLER, of Boston, in the county of Suffolk and State of Massachusetts, have' invented an Improved Machine for Producing Designs; and I do hereby declare the fol lowing to be a full, clear, and exact description of the construction and operation of the same., reference being had to the accompanying drawing and letters of reference marked thereon making a part of this spceification, in whichv Figure 1 is a perspective view of my invention;

Figure 2 is a side elevation of the same; and

Figure 3, a transverse section through line x x, fig. 2.

.lhis invention has for its object the production of ornamental configurations and designs, and consists, mainly, of a suitable case containing reflecting surfaces arranged like a kaleidoscope, and having certain appliances for holding various objects before said reflectors, and adjusting such objects in any desired position, as will hereinafter more fully appeal'.

In the drawing- A represents a horizontal box, resting on the legs a, and having hinged ends B C.

D D represent longitudinal strips within the box A, which strips are connected at their upper edges by the hinges E, while their lower edges rest upon they bottom of the box A, and form a triangle in connection with the same.

The inner sides of the strips D D are blackened and covered wit-h glass plates F F, which constitute reflectors, and the bottom of the box A is covered with black velvet or other material D".

The hinge E is, the invention of one Timothy Smith, and is provided with a spiral spring, e, which tends to keep the hinged parts D D at right angles with each other.

G represents a screw, which passes through the side ofthe box A and impinges upon the outer side of' the piece D', the piece D beingsccured to the box A by spiral springs y.

H is a transverse sliding frame, situated at one end of the. box A, and provided with a rack, I, with which meshesthe pinion J, on the longitudinal shatt K, which shaft rests iu bearings L L, beneath the box A.

M represents an auxiliary frame, sliding vertically in ways m in the frame H.

Both frames are vprovided with clamps, n, for holding a card or other object, N.

O represents a gauge on the bottom of the box A, and

o is an index or pointer attached to the piece D',

lwhich serves, in connection with the screw G, to reg- .being adjusted tothe proper angle by the screw G,

the observer looks through the triangular opening at the opposite end. The object, heilig duplicated and reduplicated by the reflecting sides ot' the pieces-i) D', forms a regular design, which varies with the slightest motion of' the frames M and H, whichl is eiiected by turning the shaft K in either direction or sliding t'he frame M up or down. v

If desired, a solid frame' may be substituted for the .open frame M, in ease an object not attixed to a card is usedin which case the light falls directly on the same ou the side nearest the beholder.

In case a transparent object is viewed, the light comes from beyond, passes through the glass It, and becomes softened and toned down.

It will be readily seen that, as the different combinations amlnduplications which may be produced by this device are endless, it may be rendered especially valuable to'carpet-manutitcturers and others who have occasion to produce new designs.

The reflected images can readily be photographed and preserved.

A disk or wheel may be substituted for the frame H, having oogs on the periphery thereof', with which the pinion .I might engage, said disk being pivoted transversely ofthe box A.

Having thus fully described my invention,

XV hat I claim as new, and desire to secure by Letters Patent, is-

lhe case A, provided with the kaleidoscopic reflectors D D, frames N and H, rack I, and pinion J, all arranged and operated substantially as described.

In testimony whereof I have signed my name tc this specification in the presence of two subscribim witnesses.

MATTHIAS KELLER.
